Divided and this application Oct. 25, 1962, Ser- 1 Claim. (Cl. 126-21) This application is a division of US. Patent application Serial No, 176,398, filed February 26, 1962, titled Oven Exhaust Structure, and assigned to the assignee of the present invention.

This invention rel-ates generally to wall-mounted domestic oven structures and in particular to such a structure having an integral fume removal system or means for exhausting baking fumes, heat and smoke from the oven.

In conventional domestic ovens, including wall-mounted ovens, the fumes, heat and smoke generated in the oven during use are vented through openings in the oven door or the stove front into the room in which the oven is located. Wall-mounted domestic ovens having fume exhausting features are not unknown in the prior art, an example being the disclosure of Weaver et a1. Patent 2,836,114. The present construction distinguishes from the prior art arrangements in that, among other things, the exhaust plenum and exhaust blower and motor are mounted Within a unitary oven structure. The oven and fume removal system are thus integral. A locator member is disposed exteriorly of the oven and interposed between the blower outlet aperture and the flue which leads to the discharge area, normally the exterior of the home in which the oven is installed. The locator member mates with abutments or positioning means on the exterior of the oven structure or cabinet so that when the oven is inserted in the wall opening, registry of the blower outlet with the flue is assured.

It is an object of the present invent-ion therefore to provide a power-exhaust type wall-mounted oven structure which can be easily and conveniently installed and serviced.

A further object of the present invention is to provide a structure of the type referred to utilizing a locator member between the blower outlet and the flue inlet to assure that registry between these members is obtained when the oven is installed.

The full nature of the invention will be understood from the accompanying drawings and the following description and the claim.

FIG. 1 is a front view, installed, of an oven embodying the resent invention.

FIG. 2 is a perspective view showing the oven about to be installed in the wall opening, having portions broken away to illustrate the means for assuring registry of the out-let and the exhaust duct.

FIG. 3 is a view similar to FIG. 2 but showing the oven after completion of its insertion into the wall opening.

Referring initially to FIG. 1, a Wall mounted oven structure embodying the present invention is shown installed or mounted within the wall 10. When installed, the visible portions of the oven include the generally rectangular frame 11 which mounts a control panel 12 within the upper marginal area enclosed by the frame. An oven door 13 is hinged in conventional fashion adjacent its lower margin to the oven structure proper. The oven structure shown in FIG. 1 also includes a lower oven door 14 also conventionally mounted by means of hinges (not shown) upon the oven structure. It will be understood that the lower oven, closed by the oven door 14, may or may not be included in the structure and the inventive features herein described can be incorporated 3,196,862 Patented July 27, 1965 in a single oven structure wherein the frame 1 1 is shorter in height so as to enclose only the oven door 13 and the control panel 12.

Referring particularly to FIGS. 2 and 3, the structure utilized in installing the oven in the wall opening and assuring that the oven exhaust aperture registers with the exterior exhaust flue upon completion of the oven installation will now be described. The oven structure itself includes a housing indicated generally at 14 having a top wall 16, side walls 17 and a base well (not shown). In FIGS. 2 and 3 the oven door 13 has been removed from the oven structure. In FIG. 2 the oven housing is shown at the initial stage of insertion into the wall opening 18, a portion of the opening being broken away to illustrate the structure. Extending vertically downward behind the wall 10 is an exhaust flue 19 which leads to a discharge area, normally the exterior of the building in which the oven is installed. The lower end of the flue 19 registers with a fitting 21 carried by an elongated locator member 22 which extends from the flue to a point adjacent the wall opening 18. An L shaped bracket 23 is adjustably positioned or mounted on the member 22 and is provided with apertures in the vertical portion for securing the vertical portion of the bracket 23 to the inner face of the wall 10 into which the oven structure is to be inserted. It will be understood that the adjustable positioning of the bracket 23 on the member 22 provides a flexibility in positioning of the vertical flue 19 with relation to the wall 10.

Mounted on the top wall 16 of the oven housing are spaced brackets 24 which accommodate therebetween the side margins of the locator member 22, the brackets 24 being formed so as to have portions overlying the marginal top surface of the locator member. The top wall 16 of the oven housing is provided with an oven exhaust aperture 26 which communicates with the outlet passage of a powered blower unit to be subsequently described.

In the installation of wall mounted ovens it is usually quite difiicult to make the outlet connection and to determine whether, after the oven unit has been inserted into the wall opening, the exhaust aperture is in register and in proper communication with the exhaust fine. In the structure as so far described, after the exhaust fine 19 has been properly installed, the locator plate 22 is secured to the wall 10 by means of the bracket 23 and the lower end of the exhaust flue is properly inserted into the fitting 21 carried by the locator member. The oven is then placed opposite the opening 18 and the brackets 24 are placed in engagement with the marginal edges of the 10- cator member 22. As the oven housing is inserted into the wall opening the sliding cooperation of the locator member and the brackets 24 guides the oven so that when the frame 11 is against the outer face of the wall 10 the exhaust aperture 26 will be in register with and in communication with the fitting 21. Proper connection of the exhaust aperture 26 with the flue 19 is thus insured when the oven is finally seated in the wall opening 18, this final installation position of the oven housing being illustrated in FIG. 3.

While the invention has been disclosed and described in some detail in the drawings and foregoing description, they are to be considered as illustrative and not restrictive in character, as other modifications may readily suggest themselves to persons skilled in this art and within the broad scope of the invention, reference being had to the appended claim.

The invention claimed is:

A structure adapted for utilization in installing wallmounted domestic ovens in a wall opening to assure that the oven exhaust aperture registers with the vertical exterior exhaust flue when the oven is inserted horizontally in to the wall opening, said structure comprising an elonq gated locator member, an L-shaped bracket carried by said member adjacent one of its ends, said bracket being adapted to be secured to the wall adjacent the Wall opening, a flue-accomodating fitting mounted on the opposite end of the member adapted to register with the external flue and with the oven exhaust aperture, and elongated abutment guide means adapted to be carried by the oven surface adjacent the exhaust aperture and to extend in the direction of movement of the oven as it is inserted in the wall opening, said abutment guide means slidably engaging the margins of said locator member to guide the oven into exhaust aperture registering relation UNITED STATES PATENTS 2,750,867 6/56 Meyer 98115 2,971,451 2/61 Feig 98--115 3,026,788 3/62 Spear "98-115 JAMES W.
